AUTOMATIC STOP FOB TALKING-MACHINES.

Speeiflcation of Letters Patent.

Patented Aug. 25, 1914.

To all whom 'it may camera:

Be it known that we, QUI'NCY A. A'rwoo) and LILLA D. ATWooD, citizens of the United States, and residents of Newton, county of Middlesex, and State of Massaohusetts, have invented an Improvement in Automatic Stops for Talking-Machines, -of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like partis.

Our invention relates to talking machines and is designed to providean improved automatic stop deviee for automatically stopping the machine at any desired point during or after the reproduction of the record tlereby.

In the drawing of the particular embodiment of our invention selected for description and illustration, Figure l is a plan of a typical talking machine cabinet top, partly broken away, showing our stop in proper position thereon for use; Fig. 2, a side elevation of the device, viewed from the front of the eabinet or lower side of Fig. 1, the same being set to stop the machine; Fig. 3, an Elevation of the opposite side of the de- Vice from that shown in Fig. 2; Fig. 4, an end elevation from the right, Fig. 1; Fig. 5, a View similar to Fig. a but showing the position of the parts after the stop has been. actuated to stop the machine.

Our improved stop in the form herein illustrated, comprises, see Figs. 1 and 2, a base 1, of suitable material, as metal, adapted to be Secured Conveniently, as by screws,

to the top 2 of a talking machine cabinet, said base being provided at convenient points Wltll posts or upright plates 3 and 4. EX- tended to one side from the upright plate or support 3 is a shoe carrying arm 5, preferably of resilient material, and so Secured to said support that it tends normally to spring toward the edge of the talking machine turn table 6, see Fig. 5. In this particular instance, the arm 5 is cut away at 7, to make it more resilient and responsive to the movement of the latch, as Will be subsequently described. At a suitable point thereon the shoe carrying arm 5 is provided with a table cngaging number or shoe 8, 'for engaging the edge of the turn or record table 6. Said shoe is shown her-ein as a strip of leather, tghtly fitted to and held in a tubular holder 9 Secured 'to the arm. This shoe member 8 extends through the arm 5 and may be forced :forward through said arm and holder as necessary to compensate for the wear thereof in use.

For looking the arm 5 and its shoe 8 in noperative or table releasing position, out of contact With the table 6, we have provided said arm with a latch member 10 shown herein as a strip of suitable material as brass, folded upon itself at one, and herein the left hand end Fig. 1, and loosely pivoted to the arm 5 by a pivot 152. One of the ends 11 of the latch is redneed in height, Figs. 9 and 3, and preferably beveled on its lower edge 13, Figs. 4 and 5, and adapted to engage a shoulder 14, or catch as a notch 15 in the plate 4. The outer or right hand end of'the arm 5, Fig. 2, or a portion of the same, may be folded back upon itself to form a guide 16, Fig. 1, to receive and guide the end of the latch 10. This latch lO'serves to retain the shoe carrying arm 5 and its shoe 8 in inoperative position relative to the turn table 6. This is the normal position of the shoe carrying arm 5 where it rests until the latch 10 is released to permit said arm to throw the shoe 8 against the turn table 6.

For releasing or unlocking the latch 10, we provide a latch releasing or unlocking lever 17, Figs. 1 to 5, herein shown as pivoted to the latch 10 by the same pivot 12 that seoures said latch to the arm 5. In order that this lever 17 may be engaged in different positions to release the latch and to stop the machine at dilierent times, it is made adjustable relative to the latch 10, but it is so Secured thereto, herein frictionally, that slight movement of the lever after it is set in position will release or unlock the latch and free the shoe to spring against the turn table and arrest the latter. The releasing lever is herein shown tightly gripped frictionally between the two sections of the latch 10 which are bent about and to tightly clasp it, while the lateh itself together with its releasing lever are easily rotatable about the pivot 12.

The base 1 of the device is Secured to the cabinet top 2 in such position between the edges 18 thereof that the latch releasing lever 17, when positioned at any point between the extreme limits of throw, as indicated by dotted lines, Fig. 2, will be engaged by the sound arm 19 as the latter swings to the left, Fig. 1, in traveling over the record. The base must also be so positioned relative to the edge of the table 6, Figs. 1 and l, that when the latch 10 is released, as shown in Fig. 5, the shoe 8 will press tightly against the edge of the table to restrain the same from rotating.

The point in the record at which it is desired to sto the table having been determined, for mstance the inner or finishing end of the record, the needle is placed at that point on the record and the lever 17 is swung nto contact with the sound arm 19, see dottcd line position Fig. l, which sets said latch lever in position to stop the machine when the sound arm in traversing the record comes into contact with it. This movement is permitted by its frietional engagement with the latch. now Sprung back to remove the shoe from contact with the turn table which releases the latter, the Shoe carrying arm being held in its released position by dropping the latch behind the locking shoulder 14. The turn table and its record having been then released, the sound arm is swung to the right, as indicated in Fig. 1, and the needle placed in the outermost turn of the groove. In Figs. 1 and 2, the positions of the outer end of the sound arm at the beginning of the record and at the end of the same may be Conveniently represented by the circles 20 in full and dotted line positions respectively. When the needle approaches the end of the groove in its travel over the record, the sound arm 19 in its travel-se across the record will have'reached the position represented by the dottcd lines in Figs. 1 and 2 and at this point it will again engage the levcr 17, turn it on its pivot 12 slightly tothe left, and raise the latch 10 from behind the shoulder 14 permitting the resilient arm 5 to spring to the left, F ig. 5, and bring the shoe 8 against the periphery of the table to arrest it. If it is desircd to arrest the record at some other point than the end thercof, the needle will, of course, be momentarily positioned at such point in the grom'e and the releasing arm lT swung to the right until it Contacts with the sound arm 19 in that position. The lntch 10 may now be dropped behind the shoulder l-l and the sound arm returned to its otermost position and the machine started as before. lYhcn the needle reaches the point in the record at which it was momcntarilypositioned and which represents the point at which it is `desircd to The shoe carrying arm is` stop the machine, the sound arm' will again engage the lever 17, move it and raise the latch 10 and permit the arm Sato.` throw the shoe 8 against the edge of the table (3.

hen it is desh-ed to operate the machine without the automatic stop, the releasing arm 17 may be turned down or depressed in the slot 21 in the top of the plate 3, Figs. l, i and 5, see dotted line position Fg. 2, below the path of travel of the sound arm 19.

This stop, although simple of Constructon and inexpensive to nanufacture, is particularly convenient and efi'ective, not only to stop the machine at the end of the groo've or the record portion ther-cof, tliereby sreventing the needle from mutilating the ace of the record in case the operator neglects to stop the machine at the proper point, or is called away therefrom while the machine is in operation, but also to stop the machine at any desired point during the reproduction of the record in case such is, for any reason, desred.

It is obvious that the talking machine may be operated using our :improved stop alone, this stop ansvvering every purpose for stopping and starting the machine, or our stop may be used in connection with the usual stop provided with the machine.

Having described one embodiment of our invention which may, however, doubtless be modified without departing from the spirit and scope of the invention, we claim:
